Vue-cli3 項目初始化備忘

准備嘗試用vue制作一個手機端的可視化應用

全局安裝vue命令

cnpm install -g @vue/cli

創建項目

進入項目存放目錄新建項目

vue create [project name]
cd [project name]

安裝插件

這里我安裝了一個代碼校驗、以及router、vuex

vue add @vue/eslint
vue add router
vue add vuex

全局CLI配置

在以往的版本中都會有個config文件作為全局配置，但是當前的版本需要自己添加  vue.config.js  ，只要在package.json同級目錄下（即根目錄）創建

const path = require("path");

function resolve(dir) {
  return path.join(__dirname, "./", dir);
}

module.exports = {
  chainWebpack: config => {
    // 為src下文件配別名，不使用相對路徑
    config.resolve.alias
      .set("@", resolve("src"))
      .set("assets", resolve("src/assets"))
      .set("components", resolve("src/components"))
      .set("views", resolve("src/views"))
      .set("icons", resolve("src/icons"))
      .set("router", resolve("src/router"))
      .set("utils", resolve("src/utils"))
      .set("style", resolve("src/style"));

    /** 設置處理svg的router，使svg可直接用名稱調用，無需路徑 */
    // svg rule loader
    const svgRule = config.module.rule("svg"); // 找到svg-loader
    svgRule.uses.clear(); // 清除已有的loader, 如果不這樣做會添加在此loader之后
    svgRule.exclude.add(/node_modules/); // 正則匹配排除node_modules目錄
    svgRule // 添加svg新的loader處理
      .test(/\.svg$/)
      .use("svg-sprite-loader")
      .loader("svg-sprite-loader")
      .options({
        symbolId: "icon-[name]"
      });
  },
  /** 開發環境代理 */
  devServer: {
    open: true,
    proxy: {
      "/api": {
        target: "http://localhost:3000",
        ws: true,
        changeOrigin: true,
        pathRequires: {
          "^/api": ""
        }
      }
    }
  }
};

接下來是一些移動端的配置

禁止頁面放大縮小

禁止移動端通過手指放大縮小頁面

頁面位置 public/index.html  

<meta name="viewport" content="width=device-width,initial-scale=1.0,minimum-scale=1.0,maximum-scale=1.0,er-scalable=no">

FastClick

為避免瀏覽器兼容問題引起的點擊問題（部分瀏覽器對點擊事件有300毫秒的延遲響應機制）

import fastClick from "fastclick"

if ("addEventListener" in document && "ontouchstart" in window) {
  FastClick.prototype.focus = function(targetElement) {
    targetElement.focus();
  };
  document.addEventListener(
    "DOMContentLoaded",
    function() {
      FastClick.attach(document.body);
    },
    false
  );
}
